We are going to run a bunch more benchmarks when I get back, probably 
doing things like turning on htrees and tail combining and stuff, in 
lots of different combinations.  Ordered mode will be added, as well as 
making green have a uniform meaning for all the benchmarks;-).  This 
benchmark was just what could be done before I got on a plane.
